Set-up clearance

Q200 (incremental value): Distance

between tool tip and workpiece surface.

Workpiece surface coordinate

Q203 (absolute

value): Absolute coordinate of the workpiece surface

2nd set-up clearance

Q204 (incremental value):

Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.

Plunging strategy

Q366: Type of plunging strategy.

„

0 = vertical plunging. The TNC plunges
perpendicularly, regardless of the plunging angle
ANGLE

defined in the tool table.

„

1 = helical plunging. In the tool table, the plunging
angle ANGLE for the active tool must be defined as
not equal to 0. The TNC will otherwise display an
error message. Plunge on a helical path only if there
is enough space.

„

2 = reciprocating plunge. In the tool table, the
plunging angle ANGLE for the active tool must be
defined as not equal to 0. The TNC will otherwise
display an error message.

Feed rate for finishing

Q385: Traversing speed of

the tool during side and floor finishing in mm/min.
